Create a complete AM system simulated in Matlab. The carrier will be equal to:

The initial input signal will be equal to:

The second signal will be an audio signal available in the folder as a .wav file.

The system consists of modulating the AM signal and transmitting it through a channel with additive Gaussian noise, so that we can modify the modulation index and the power of the noise. Thus, it will be possible to study the performance of the system in different signal to noise reasons. After passing the AM signal through the simulated channel, the signal must be properly demodulated and recovered.

c(t) = cos(21. 100.000 - t) si(t) = cos(21 100 t) + cos(26 4.000 - t) + cos(27 20.000 - t) c(t) = cos(21. 100.000 - t) si(t) = cos(21 100 t) + cos(26 4.000 - t) + cos(27 20.000 - t)
